Dirty Philadelphia Is Dirty

This time? It's the air.

NBC 10 says the American Lung Association has bad news for Philly in a new report: “Ozone levels (commonly called smog) came in worse than it did in the 2009 data, likely due to warmer temperatures in 2012. Philadelphia County remained the most polluted county in the metro area as well as in Pennsylvania, and was graded “F,” significantly worsening its annual average to 16.7 days with unhealthful levels of ozone in 2010-2012, from 10.7 in 2009-2011.” The report said Philly tied for 11th — not an honor — for year-round particle pollution.
